Pottstown, Pennsylvaniahas a four-season climate typical of the eastern mid-Atlantic region – that is to say the weather is unpredictable. The Atlantic Ocean, just 50-60 miles to the east and the Appalachian Mountains to the west all have a moderating effect on the region’s weather. Pottstown has winters that are cold but not sub-freezing. Some years there is very little snowfall and others feature one snowstorm after another. Summers are hot, but tolerable, except when the humidity is very high, as is often the case in July and August. Spring and fall tend to have mild temperatures and are often the most enjoyable seasons of the year. Rainfall is spread throughout the year, with thunderstorms possible in spring and summer.
